Application tiled September 20, 1913. Serial N o. 790,833.

To all whom t may concern Be it known that I, BANNER M. BROOKE, citizen of the United States, residing at Columbus, in the county of Franklin and 'State of Ohio, have invented aA certain new anduseful Improvement in lVeighing- Scales, of which the following isa specifcation.'

The invention relates more especially to what arekcalled quick indicating scales and bearing used in Vat has' for its object t0 provide an improved and simplified construction dispensing with racks, l pinions, springs and parts greatly subject to deterioration and also in which fifictionalid the"possibility of the generation v o duced .to a minimum.

The invention is embodied in the examples herein particlilarly shown and described and then pointed out in the claim.

Eigre '1" is a general view of the front of theta paratus, parts being in elevation fand part) in sectionJf/Fig. 2 is a detail of a. the wv'pendent Weight beam. Fig. 3 is afi/(dtail pf a bearing between the pendent weight/ beam and the indicator. ig. 4 isa view like Fig. lbut omitting the upper .portion of the structure to illustrate amodi'ication. ,f f j f "In the views 5 designates-the' frame of. an

y ordinary platform/sc le which 'is equipped for the application o my invention with a horizontal eros piece 5?.: f

Referringmgre particularly to the -constructionshownfig. 1, the character 6 designatesthe lseal,gibeainful/crumed as usual on 'apairf of agategbeaings like that at 7a in the beam hanger 7 and having a sliding poise' 8 as Well as an adjustableA balance ball ,'9. 'Thescale beam h'as any suitable scale 6a. Themcharacter 10 designates a shelf lever loosely hung at 1 1-to and under the lower member of the frame. Connected with said shelfjlever 10 is theusual steelyard rod 12 ,of the platform (not shown) and connecting the free end of said shelf lever with the shank of the scale beam 6 is the beam rod 13.v The end of the long arm of thescale beam oscillates in a'trig 'loop 14. The end of the scale beam beyond the loop ,14 has loosely connected to 'it' a counter poise stem 15 that extends through an opening in the/ frame member 5 to the pendent weight beam 16. ,Thesaid pendent weight'be/amis provided at one end ing a Vpin-pivot 18; and the stem 15 is profrictin by foieign obstructionsis reupon thc platform of the sufficient weight from. the gravity lever to -l f loogly cally exactly sufficient to bring the indicator y The total weight vided With a stirrup 19 having a socket bear-l ing 20 to receive the pin pivot 18 as shown designates an oscillating indicator arm Y ght beam contains la.

The indicator arm is balanced by a wei ,htl

A suitable eccentric member 25 on the axis 'of the indicator has connected with it a.`

H exible metallic strap 26 that rides ori-'fthe rim of the eccentric.

on the opposite side of the fulcrum 24. i 7o;

The indicator arm. is ,v

also provided with a suitable adjustable penj l dulum weight 27. The strap 26`has con nected to it, at its lower end, a hook member 28 provided with an adjustable. pin'pivot 29 engaging a socket bearing 30 on a loop 31 on the pendent weight beam.

32 designates a dash pot containing a suitable liquid in which Works a plunger 33 connected with the pendent Weight beam, said liquid being adapted to retard the oscillation ofthe parts.

34 designates a dial having a suitable scale 34a arranged on an arc path of the indicator arm 23.

The Weight beam 6, its necessary appurtenances and its operating mechanism, may be said to be the primary Weighing mechamsm. f l

thousand pounds by fives on each. scale for example. If in the instance vdescribed or indicatingA r t5 pounds be placed scale it will release the scale beam be at balance zero and one thousand allow the pendulum to descend automati-A a thousand pounds on the dial, and if any fraction of said Weight be placed upon the platform the weight thereof will likewisebe indicated at the proper pointon the dial. of any load imposed upon the platform, and within the `weighing capacity of the scale, is indicated by the-sum i of the Weights indicated bythe tivo scales, such Weight being quickly-ascertained ,by I' reason of the quick oscillation of the indicator to a condition of rest at the proper 1 mark` on the dial. It is, of course, the oscilbeam rod'la thereby elevating the loop 31".
